Chuba Hubbard, Oklahoma State’s Heisman contender, is threatening to sit out of all team activities after seeing a picture posted of head coach Mike Gundy wearing a t-shirt promoting One America News Network, a right-wing station.

“I will not stand for this,” Hubbard tweeted. “This is completely insensitive to everything going on in society, and it’s unacceptable. I will not be doing anything with Oklahoma State until things CHANGE.”

Hubbard, the reigning Big 12 Offensive Player of the Year, could have been selected as high as the second round in April’s 2020 NFL Draft, but opted to return to Stillwater for his junior season. Last season, he ran for 2,094 yards and 21 touchdowns.

All-Big 12 linebacker Amen Ogbongbemiga quickly supported his star teammate.

“I stand with him!” Ogbongbemiga tweeted.

As did offensive lineman Treven Jenkins: “As an O-line we stand and support Chuba.”

The support even came from at least one former Cowboys player, Baltimore Ravens running back Justice Hill, who tweeted his “100% support.”

“OSU Athletics and University need major change,” he wrote.

In a statement issued later Monday, Oklahoma State athletic director Mike Holder said “This afternoon has been very disturbing. The tweets from the current and former players are of grave concern.”

Gundy, 52, has led the program since 2005, producing a 129-64 record, with one Big 12 title. The Oklahoma native and former Cowboys quarterback had recently described the controversial content of OAN as “refreshing.”

“They just report the news,” Gundy told The Oklahoman. “There’s no commentary. There’s no opinions on this. There’s no left. There’s no right. They just report the news.”
